R.I.P Cecil the lion!, page-4

How do you know he went through the correct channels? He's already been convicted of lying to authorities in relation to hunting, his claims carry no weight whatsoever:

"Cecil's killing doesn't appear to be the first time Palmer has gotten into trouble while hunting.
A man by the same name and age, and from the same town, illegally killed a black bear in Wisconsin several years ago, according to court documents.
That individual pleaded guilty to making false statements knowingly to the U.S. Fish and Wildlife Service, and was sentenced to one year on probation and ordered to pay a fine of nearly $3,000, records show.
A New York Times article in 2009 that profiled Palmer and his hunting methods said he had served a year of probation over the false statements case."

Part of the fault lies with Mugabe, though, for allowing killing of lions at all.
